Abstract
The Rhizobium strains associated with Ailacrotyloma uniflorum were found to be highly salt tolerant. Hence, the effect of other common inorganic salts on the growth of these rhizobia was also studied. These rhizobial strains showed tolerance to calcium chloride and sodium sulphate up to 1M. Potassium carbonate was tolerated by these strains at 0.5M. Calcium carbonate, magnesium sulphate and potassium chloride were found to be beneficial to the growth of all strains even at 1.5M concentration. These Rhizobium strains can be used to improve the cultivation of legumes in saline soils.
